Abstract

The utility model provides a convenient practical connecting member for shutterings, comprising an inner pull rod, a wax apple head, an outer pull rod and a pressing plate, wherein, the inner pull rod is inlaid in the concrete wall; two bolt grade segments of the inner pull rod are connected or coated with the whole wax apple head shaped by high-strength concrete; the center of the wax apple head is provided with a sleeve pipe with a bolt hole; one end of the sleeve pipe is provided with a flange which is bulged in the radical direction and blocked with the end surface of the concrete main body; the other side of the wax apple head provided with the flange is a hollow concave hole; because the wax apple head is in the shape of a prism with slot edges and the main body is shaped by the concrete which is easy to be combined with the wall, the utility model has the advantages of fastness and no need of dismounting.

Description

Connecting member for shutterings

The utility model relates to a kind of setting that is connected and fixed, particularly a kind of building form serrenoeud.

The structure of present template serrenoeud as shown in Figure 1 to Figure 3, Fig. 1 is the result of use figure of template serrenoeud.It comprises one bury the draw-in bar 2 that is placed in the concrete, with draw-in bar two thread segments 21 wax apple head 1 of the company of twisting mutually, two outside links 3 install with pressing plate 4 activities, the two outer inner segments that draw connect with wax apple head 3 is stubborn mutually after passing template A, twist on outside link 3 thread segments in pressing plate 4 outsides and be rotary with locking nut 5, pad is placed with angle section B between pressing plate 4 inboards and the template A outside.Wax apple head 1 generally all adopts plastic material to make, and after the concrete perfusion form removal, then its folding must be removed, because the wax apple head of plastic cement material can not combine well with surrounding concrete.Therefore, when removing, must screw, often cause the loosening of draw-in bar 2, cause inner screw and its periphery to produce gap H, even draw-in bar can be taken out of.So all can cause infiltration space or cavity, cause hidden danger to building, in addition, splitting out of wax apple head must be removed one by one by manually ascending a height, like this, it is time-consuming not only to require great effort, and must etc. concrete curing to half-dried or absolutely dry after just can remove, so it is bigger to construction speed influence.

The purpose of this utility model just is to overcome the above-mentioned shortcoming and defect of existing in prior technology, and provides a kind of concrete wax apple head that need not remove that has, the template serrenoeud that saves labor.

The purpose of this utility model is to realize by following technical scheme, and it is by draw-in bar, wax apple head; Outside link and pressing plate constitute, wherein, the draw-in bar potting is in concrete wall, the monolithic wax apple head that connection or cladding have the strong concrete moulding to form on the tow spiro stage section of draw-in bar, wax apple head the center one sleeve pipe that has a screw is arranged, sleeve pipe one end have radially projection and with the flange of its outer concrete wax apple head body end face block, the opposite side that is provided with flange of wax apple head is the shrinkage pool of hollow, because wax apple head is the rib body shape that has the groove rib, form with the married concrete formation of body of wall for being easy to and add its main body, thereby it has in conjunction with firmly and need not roll over the advantage of removing.

Therefore: remarkable result of the present utility model is:

The 1st: because wax apple head is that strong concrete is made of one piece, thereby it and concrete wall have good binding, so need not to remove one by one, also just can not cause becoming flexible, deviating from of draw-in bar certainly, also can not produce the problem of body of wall percolating water.

The 2nd: because of can avoiding removing wax apple head, but thereby saving of work and time, accelerating construction progress.

The utility model concrete structure is realized by the following examples and accompanying drawing thereof:

Below in conjunction with accompanying drawing 3-12 concrete structure of the present utility model is described in detail:

The utility model has a draw-in bar 2, what twist to connect mutually with 2 liang of thread segments 21 of draw-in bar is two wax apple heads 1, one end of the outer outside links of visiting 3 of two correspondences respectively pass after the pressing plate 4 of side separately and the template with body of wall in wax apple head 1 inner bolt hole 111 company of twisting mutually, on the outside link 3 in the outside of pressing plate 4, screwed locking nut 5, it is characterized in that: the body 11 that has inner bolt hole 111 is arranged by the integrated wax apple head 1 inner cladding of concrete, the axial length of the endoporus 13 of wax apple head 1 is greater than the axial length of the cladded body 11 in it and leave an indent and fill out mouth, between body 11 and wax apple head 1 end face block flange 12 is arranged.Referring to Fig. 4 to Fig. 6 and Figure 10 to Figure 12

Architectural feature of the present utility model also is:

The outer surface of the integrated wax apple head 1 of high-intensity concrete is provided with along the circumferential spaced apart and fin 14 of parallel distribution vertically.Referring to Fig. 4, Fig. 6, Fig. 8-Figure 10

One end of the circular or prismatic endoporus 13 of the integrated wax apple head 1 of high-intensity concrete is inserted to be embedded into a body 11 that has an inner bolt hole 111 again, body 11 radially flange part 12 blocks of projection on the outer face, aperture of circular or prismatic endoporus 13, body 11 bodies are along circular or prismatic endoporus 13 certain length that extends internally, and the segmentum laterale of circular or prismatic endoporus 13 and body 11 covers are joined place's nature and formed an indent and fill out a mouthful C.Referring to Fig. 6, Fig. 9 and Figure 10

Profile and endoporus 13 with slotting embedding cladding section circular or prismatic endoporus 13 body 11 matches, and the outside of flange of pipe body portion 12 outwards has an extension vertically.Referring to Figure 10 to Figure 12

The coarse rib nonreentrant surface that is shaped as circle of the longitudinal section of the integrated wax apple head 1 of high-intensity concrete or prismatic.Referring to Fig. 4, Figure 11

The appearance body section of the integrated wax apple head 1 of high-intensity concrete is shaped as total length uniform section or variable cross-section vertically.

So-called uniform section or variable cross-section, the appearance body that is to say wax apple head 1 can be circle, referring to Figure 11, or many prismatics, also can be Taper Pipe shape, the purpose of the variable cross-section design of many prismatics or taper be for make its with the body of wall cast after have better mutually the embedding associativity and prevent to rotate the effect that gets loose.Because will change stubborn when removing outside link 3.And also be to prevent to rotate in the purpose that circular surface adds fin 14.

The utility model using method is basic identical with prior art.See Fig. 8 and Fig. 9, and difference is arranged greatly on the result of use, Here it is: wax apple head 1 need not remove, both the saving of labor was saved trouble, because it is that material of the same race is made with body of wall, do not stay the gap so be easy to mutually combine again, and because stubborn tear wax apple head 1 open stubborn of nothing torn action open, so draw-in bar 2 can not become flexible or deviate from yet, cause wall leakage, leak with eyelet so can never cause because of gapped.

And behind the dismounting exposed part, fill out a mouthful C because of having only a very little indent, so available water silt stone is is conveniently filled and led up it.Referring to Fig. 9
